SPECIFICATION forming part of Letters Patent No. 509,857, dated December 5, 1893.

Application filed February 3. 1892- Serial No. 420,175. (No model.)

To all whom it may concern.-

Be it known that I. SAMUEL L. ALLEN, a citizen of the United States, residing at Cinnaminson, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Cultivators, of wh ch the following is a full specification.

My in vention relates to cultivators and conslsts of certain improved features, therein having special reference to the manner of securing certain of the parts together, to the construction and operation of the marker to the manner of varying the depth of out of the implement, &c., as hereinafter fully detailed.

Referring to the accompanying drawings: Figure 1 is a side elevation of a cultivator embodying my improvements. Fig. 2 is a plan view thereof with the handle levers broken away. Fig. 3 is an enlarged transversesectional View in the plane of a: a: Fig. 2. Flg. 4 is an enlarged longitudinal section through the marking iron, and Figs. 5, 6 and 7 respectively represent on an enlarged scale a plan View, a side elevation and an end elevation of the bearing box or block at the rear of the side bar.

A is the central bar and B B the two side bars of the cultivator frame.

E E are the handles connected at their front ends to the central bar and supported by the brace I and the bracket I, the bracket being bolted to the central bar and the brace to the bracket.

The side bars B B are hinged between the plates 0 0 near the front end of the central bar and are connected at their rear ends with the expanders F F through the bearing blocks L, presently to be described. The inner ends of the expanders F are pivoted to lugs on the bracket 1 which supports the handle brace I.

F is an open handle lever pivoted at f to a sliding piece F on which is mounted the toothed piece F a handle operated stop or pawl within the open lever F engaging with said toothed piece F as the lever is set in any angular position.

J is a connecting piece between the lever F and the bracket 1', while F F are arms pivotally connecting the arms F with the sliding piece F the whole construction and operation of the hinge plates, side bars, ex-

panders and handle lever being in the main similar to the corresponding parts shown and described in my United States Letters Patent No. 466,282, dated December 29, 1891.

An important variation exists however be tween the manner of connecting the expanders F to the side bars B in the present case, and that shown in my previous cultivator patents, No. 387,332, dated August 7, 1888; No. 424,946, dated April 8, 1890, and the above named patent, No. 466,282, dated December 29, 1891. In all three of these last mentioned patents a bearing block is bolted to the rear of each side bar and a tooth having a standard similar to G Figs. 1 and 2 is secured near the rear of each side bar by having a staple bolt pass up through the tooth standard and through holes in the bearing block, said bolt being provided with nuts on the top of said block. In all three of the above patents moreover the outer end of the expander bar is interposed between the tooth standard and the bearing block and has one leg of the staple bolt pass through said expander, thus securing it in place. By this mode of connection it will be seen that the tooth with its standard similar to G cannot be removed from the frame without severing the connection between the expander and the side bar since the staple bolt must be removed. In my present application I obviate this difficulty by so constructing the bearing block that the expander is connected thereto by a bolt separate from the staple bolt.

L is the bearing block secured to the side bar B by bolts Z passing through the holes Z (see Figs. 5, 6 and 7) and through the bar. The block L has the usual holes Z through which pass the legs of the staple bolt Z (Figs. 1 and 2) which staple bolt secures the standard G of the tooth G to the block. The block L is provided with the lugs or ears L between which the end of the expander F fits, a bolt Z serving to hold the expander pivoted between said ears. By this construction the staple bolt Z may be removedwithout disconnecting the expander.

D is the depth regulating wheel the purpose of which is similar to that of the wheel D in my United States Letters Patent No. 463,609, dated November 24, 1891. There are important differences between the construction and operation of" the wheel controlling handle lever and adjacent parts in the present case and in the said Patent No. 463,609. In the said patent the depth regulating wheel 5 is journaled in what is virtually a single open rigid lever, fulcrumed directly'to the frame having the operating handle pass directly backward on the side of the fulcrum opposite the wheel. In said Patent No. 463,609, the convexly curved tooth-piece with which the handle operated stop or pawl within the open lever engages, is on the side of the fulcrum next the operator, being" bolted directly to the central bar.

By my improved construction as shown in my present application Ichange the leverage in such a -manner'as to 'better controlthe operation of the'depth regulating wheel. To this end-thewheel D is journaled within the open curvedarm D whichis pivoted at its rear end at d to the central bar A, the side bar being. broken away in Fig. l to clearly showthis'arrangement.

The open handle D is rigidly bolted at 01 to the ar-m-D onthe same side of the pivot or fulcrum-d, as the wheel-D and the handle is further braced by being bolted at d to the connection D of the arm D. The convexly curved-tooth-piece C with which the handle 0 operatedstop-d within the bar D engages, is bolted to the upper hinge plate 0 by the same bolts 0,-Figs'l and 2, that secure the upper and'lower hinge plates 0 C together, and tothe central bar. The tooth piece (J is thus 5 arrangedon the opposite side of the fulcrum d tothe operator, between said fulcrum and the-wheel D. It will be observed that the handles F and D in Fig. 2 are broken away *near: their lower ends soas to show more 40 clearly thepartslying beneath. Aside from theregulating wheel D the depth of-cut of the implement teeth may be regulated by means of the side runners H,

the-upright portions of which are provided 5 with aseries of holes h, whereby they maybe bolted at varyingheights to the downwardly bent portions of the bars H. The horizontal portions of the bars H pass each other throughthe clip K, (see Figs. 1, 2 and3,) beneathithe side bars B B. The clip K rests on the central bar A and is provided with the bolt lcwhich when screwed tightlydown upon the top'of the central ban-firmly clamps the barsH with the runners H attached thereto between the bottom of the central and side bars and the portion 7a of the clip.

By varying the height of the runners H, on the bars H, the depth of cut of the implement teeth is varied when the wheel D is not used for this purpose and the position of the runners laterally may be varied at will in a manner readily apparent.

An important feature of my invention consists in the peculiar construction and operation of themarking devices.

I employ for the purpose of marking the rows, two sets of similarappliances oppositely mounted, one for each side of the implement and so arranged that one of the marking irons may be raised while the other is in use.

R R are two bars preferably of wood passing across the handle bars E near the bottom thereof, and having secured thereto the marking devices:

S is a metal plate which, with the staple bolts T serve to clamp the bars R R on the handle bars. The staple bolts T embrace the bars R R and-also the handle bars E in the manner shown in Figs. 1 and 2, and when the nuts on said bolts are screwed down above the plate S, the bars R R are firmly held'in place. The rod R has'near its outer end-thehook n,- and farther in, the-screw eye 0" on the rear side of the bar. The bent rod N'N is mounted" to turn in the screw eye and hook as bearings, and has pivotally mounted onthe rear end thereof the marking iron M. This marking.

iron is made somewhat in the shape of aflat', rectangular pan having the opening m at the front thereof and the sharp edge on along'ith'e bottom, being so shaped that when in use it will cut into the ground'and load up with earth the proper weight, to make'a clear mark.

The upward and inwardly bent end'N of the rod N acts as a handle to determine'theposition of the marking iron M.

P is a seat for the markerh'andle'N- being? bolted to the bar R, as shown and prov ded with the notch p in which the said handle N may rest when the markingiron is lifted-off v the ground. I.

The rod N with its handle N 'mounted 1n bearings n r with which the bar R is provided, and the marking iron M as well as the seat 29 are identical in construction with the similar parts N N n r and P connectedwith the bar R. The drawings represent'the marker M in position for use and the marker M raised up off the ground, the handle N being. hookedinto the notch 10'. from its peculiar shape is light so that it car The marking iron ries easily when raised up.

The bars R B may be graduated along their rear sides so that they may readilybe set to overlap each other more or less as'de sired, making a mark at any distance to one side of the center.
